Re: AC current measurement with a current transformer

One easy thing to do is connect the secondary to a variac, through a
small resistor, and scope the waveform across the resistor. Increase
the variac output until you see obvious saturation, a spikey non-sine
waveform; that gives you a hint of the sort of burden voltage that
matters.

This is an excellent suggestion for any unspecified CT being salvaged for reuse. Wish I had thought of it.
